Most of us feel like there's a "me" behind our eyes, a thinker of our thoughts and author of our choices. Author and Waking Up founder Sam Harris argues that when you look closely enough, that self disappears. Dr. Heather Berlin and Dr. Christof Koch dig into why the sense of self may be something the brain constructs moment to moment, and why free will, in Sam's view, doesn't hold up to either ph

Theoretical physicist Dr. Michio Kaku joins hosts Dr. Heather Berlin and Dr. Christof Koch to explore what physics can teach us about consciousness and reality itself.

Dr. Lisa Feldman Barrett, psychologist and neuroscientist, joins hosts Dr. Heather Berlin and Dr. Christof Koch to unpack her theory of constructed emotion: the idea that emotions aren't hardwired reactions but stories the brain builds to explain physical signals like a racing heart or a furrowed brow.

Even though our experiences are shaped by unconscious patterns and bodily sensations, we have the agency to actively transform them simply by staying present and aware. Dr. Heather Berlin and Dr. Christof Koch sit down with Stanford neuroscientist and “Huberman Lab” host Andrew Huberman to explore the science of how your brain and body talk to each other, and how you can use that conversation to y
